Species-specific regulation of XIST by the JPX/FTX orthologs

Olga Marie Louise Rosspopoff

X chromosome inactivation (XCI) is an essential process, yet it initiates with remarkable diversity in various mammalian species. XIST, the main trigger of XCI, is controlled in the mouse by an interplay of lncRNA genes (LRGs), some of which evolved concom ...

Prenatal auditory experience and its sequelae

Lukas Vogelsang

Towards the end of the second trimester of gestation, a human fetus is able to register environmental sounds. This in utero auditory experience is characterized by comprising strongly low-pass-filtered versions of sounds from the external world. Here, we p ...

DUX-family transcription factors regulate zygotic genome activation in placental mammals

Didier Trono, Evaristo Jose Planet Letschert, Julien Léonard Duc, Sonia Verp, Andrea Coluccio, Alberto De Iaco

In animal embryos, transcription is mostly silent for several cell divisions, until the release of the first major wave of embryonic transcripts through so-called zygotic genome activation (ZGA). Maternally provided ZGA-triggering factors have been identif ...

Brain network characterization of high-risk preterm-born school-age children

Jean-Philippe Thiran, Alessandra Griffa, François Lazeyras, Elda Fischi Gomez

Higher risk for long-term cognitive and behavioral impairments is one of the hallmarks of extreme prematurity (EP) and pregnancy-associated fetal adverse conditions such as intrauterine growth restriction (IUGR). While neurodevelopmental delay and abnormal ...

Transcriptomic regulations in oligodendroglial and microglial cells related to brain damage following fetal growth restriction

Yohan Van de Looij, Maxime Olivier Baud

Fetal growth restriction (FGR) is a major complication of human pregnancy, frequently resulting from placental vascular diseases and prenatal malnutrition, and is associated with adverse neurocognitive outcomes throughout life. However, the mechanisms link ...

Bidirectional Transfer Study of Polystyrene Nanoparticles across the Placental Barrier in an ex Vivo Human Placental Perfusion Model

Lionel André Maurizi

BACKGROUND: Nanoparticle exposure in utero might not be a major concern yet, but it could become more important with the increasing application of nanomaterials in consumer and medical products. Several epidemiologic and invitro studies have shown that nan ...

Engineered cell instructive matrices for fetal membrane healing

Iatrogenic preterm prelabour rupture of fetal membranes (iPPROM) occurs in 6-45% of the cases after fetoscopic procedures, posing a significant threat to fetal survival and well-being. The number of diagnostic and therapeutic prenatal interventions availab ...

Conjugates containing sequences from placenta growth factor and their use as components of biomaterials and in medicine

Jeffrey Alan Hubbell, Priscilla Suhasna Maithili Briquez

Embodiments of the invention are described, including materials and methods for making molecules and materials that have a specific binding domain of a P1GF2. Embodiments include, for instance, medicaments, biomaterials, biomolecules, molecular fusions, an ...

Transfer studies of polystyrene nanoparticles in the ex vivo human placenta perfusion model: key sources of artifacts

Heinrich Hofmann, Lionel André Maurizi

Nanotechnology is a rapidly expanding and highly promising new technology with many different fields of application. Consequently, the investigation of engineered nanoparticles in biological systems is steadily increasing. Questions about the safety of suc ...

The evolution of lncRNA repertoires and expression patterns in tetrapods

Anamaria Necsulea

Only a very small fraction of long noncoding RNAs (lncRNAs) are well characterized. The evolutionary history of lncRNAs can provide insights into their functionality, but the absence of lncRNA annotations in non-model organisms has precluded comparative an ...

Growth Factors Engineered for Super-Affinity to the Extracellular Matrix Enhance Tissue Healing

Jeffrey Alan Hubbell, Melody Swartz, Priscilla Suhasna Maithili Briquez, Esra Güç, Stéphanie Elisabeth Metzger

Growth factors (GFs) are critical in tissue repair, but their translation to clinical use has been modest. Physiologically, GF interactions with extracellular matrix (ECM) components facilitate localized and spatially regulated signaling; therefore, we rea ...

The Channel-Activating Protease CAP1/Prss8 Is Required for Placental Labyrinth Maturation

Friedrich Beermann, Simona Frateschi

The serine protease CAP1/Prss8 is crucial for skin barrier function, lung alveolar fluid clearance and has been unveiled as diagnostic marker for specific cancer types. Here, we show that a constitutive knockout of CAP1/Prss8 leads to embryonic lethality. ...

A Subpopulation of Smooth Muscle Cells, Derived from Melanocyte-Competent Precursors, Prevents Patent Ductus Arteriosus

Friedrich Beermann

Background: Patent ductus arteriosus is a life-threatening condition frequent in premature newborns but also present in some term infants. Current mouse models of this malformation generally lead to perinatal death, not reproducing the full phenotypic spec ...

Synthesis of 2-(1-aminocyclopropyl)pyrrolidine-3,4-diol derivatives applying titanium-mediated reaction conditions

Pierre Vogel

The titanium-mediated cyclopropanation reaction using Ti((OPr)-Pr-i)(3)Me/EtMgBr/BF3 center dot OEt2 has been applied to various 2-cyanopyrrolidines for the synthesis of functionalized 2-(1-aminocyclopropyl)pyrrolidine-3,4-diol derivatives (dideoxyiminoald ...

Prenatally engineered autologous amniotic fluid stem cell-based heart valves in the fetal circulation

Peter Modregger

Prenatal heart valve interventions aiming at the early and systematic correction of congenital cardiac malformations represent a promising treatment option in maternal-fetal care. However, definite fetal valve replacements require growing implants adaptive ...

Placental rescue reveals a sole requirement for c-Myc in embryonic erythroblast survival and hematopoietic stem cell function

The c-Myc protein has been implicated in playing a pivotal role in regulating the expression of a large number of genes involved in many aspects of cellular function. Consistent with this view, embryos lacking the c-myc gene exhibit severe developmental de ...
